Time to update your Adobe Flash player installation again.
The latest updates fixes at least five vulnerabilities, several of them considered to be critical. You could become compromised by simply visiting a website that's hosting a malicious Flash movie.
Depending on which browser(s) you use, it might take a couple of visits to the Adobe site to update appropriately - make the visit in your Internet Explorer browser, then Firefox, Opera, etc. if you're not using a product like Secunia PSI.
Do it soon - the bad people are waiting to get you.
